Patent number: 11936113Abstract: An antenna array assembly comprises a ground plate, a linear array of patch radiator elements disposed in a spaced parallel relationship with a first face of the ground plate, and a first, second, third and fourth elongate passive radiator, each comprising one or more substantially planar conductive parts which are electrically isolated from the ground plate. The first and second elongate passive radiators are disposed symmetrically on either side of the linear array and parallel to a centre line of the linear array, on the same side of the ground plate as the linear array. The third and fourth elongate passive radiators are disposed further from the linear array than are the first and second elongate passive radiators. Each of the third and fourth elongate passive radiators is narrower than and projects further from the ground plate than does each of the first and second elongate passive radiators.Type: GrantFiled: November 23, 2021Date of Patent: March 19, 2024Assignee: Cambium Networks LtdInventors: Jomon Thomas, Deepu Nair, Visalakshy Tc, Nigel King, Varun Hegde

Patent number: 11303044Abstract: A main antenna arrangement is configured to receive with a pre-configured first directional radiation pattern having a first beam with a first beamwidth and to provide first received signals at a first output, and at least one auxiliary antenna is configured to receive with a pre-configured respective second directional radiation pattern having a second beam with a second beamwidth, different from the first beamwidth and to provide second received signals at a second output. Interference cancelling circuitry is configured to control the amplitude and phase of the second received signals received from the at least one auxiliary antenna to produce weighted second received signals and combine the weighted second received signals with the first signals received from the main antenna arrangement to reduce a level of interference signals received by the main antenna arrangement in relation to a level of wanted signals received in the main antenna arrangement.Type: GrantFiled: August 27, 2020Date of Patent: April 12, 2022Assignee: CAMBIUM NETWORKS LTDInventors: Antony Jamin, Peter Strong, Nigel King

Patent number: 10458510Abstract: A system for securing a powertrain component to a body structure of a vehicle may include first and second mounts each having a base and a first elastomeric barrier secured to and extending from the base defining an air filled chamber, and a connector coupling the air filled chambers, the connector sized to provide an associated air volume that reduces stiffness of the first elastomeric barrier at an excitation frequency corresponding to a target engine speed. The air filled chambers may be hermetically sealed and pressurized above atmospheric pressure. The system may include a fluid-filled switchable mount having a decoupler air pocket selectively coupled to a vacuum source or atmosphere with an expander integrated with the mount or as a separate component coupled between the decoupler air pocket and the vacuum source. The expander may be implemented as a Helmholtz resonator or may include an in-line expansion chamber.Type: GrantFiled: June 12, 2018Date of Patent: October 29, 2019Assignee: Ford Global Technologies, LLCInventors: Thomas Mathai, Hassan Dakhlallah, Nigel King, James F.

Patent number: 10453029Abstract: An audit system automatically ensures compliance with relevant policy by identifying an entity offering a non-audit service that also provides audit services to the enterprise, and ensuring the service is permissible and proper approval has been obtained. If the non-audit service is prohibited or proper approval from an audit committee has not been obtained, execution of the service is prevented. When a permissible non-audit service is executed, this service can be monitored and execution suspended when circumstances change such that the service is no longer permissible or approval for the service expires. The audit system can forward a message to the audit committee or other authority about any suspended business process. If the audit committee subsequently approves the suspended permissible non-audit service, execution of the instance of the business process resumes. The audit system determines whether the vendor entity was paid demands a refund where necessary.Type: GrantFiled: July 31, 2007Date of Patent: October 22, 2019Assignee: ORACLE INTERNATIONAL CORPORATIONInventor: Nigel King

Patent number: 9786074Abstract: An embodiment provides a timeline upon which a playhead indicator is moved or positioned. Changes to a displayed graph that are within a predetermined interval of the playhead indicator's time position are shown graphically on or near the graph. Actor icons are positioned on or near the displayed graph. The actor icons correspond to different entities (e.g., a person, group, organization, software agent, etc.) that has made a change to the graph. Action beams are displayed to show changes to the graph. As playback of the change events occurs, beams emanate from actor icons to items in the graph that are changed or otherwise operated upon. Various characteristics of the beams' use, appearance and behavior are described.Type: GrantFiled: October 31, 2016Date of Patent: October 10, 2017Assignee: Orcale International CorporationInventors: Ken Beckett, Reza B'Far, Ryan Golden, Nigel King, Kent Spaulding, Todd A.
